Bor C. Jackson, a

I citizen of the United States, residingat Dayvletters and figur l ton,in the of Ohio, have invented certain new and use- Aful "Improvements inElectrical Checker- Boards; and :I dorvdeclare the. following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame,.reference being had to. the accompanying drawings, and tothethereon, which form a. part of thisnspecication. 9

This invention relates -3 is a diagrammatic view of the electricalconnections; and Fig. 4 is a perspective view of one of the metalliccheckers.

VReferring more particularly to the drawings, the board consists of aface or upper side member 1 upon which the checker spaces are arranged,and the ends of which are provided with pockets 2 formed by depressedportions 3. There is a pocket 2 for each player, and said pockets areadapted 'to be closed by hinged lids 4 for the purpose hereinafterdescribed. The face member 1 is supported on the sides 5 and ends 6 of abox which is provided with a bottom 7, and

n which houses the electrical connections. The

" nected with a common conductor 12. The

common conductor 12 is provided with a source of electrical energy 13,and an indicator such as a, bell 14. The pins 10 in the nor c. mensen,`for DAYTON, omo.

"154 of which there 'is' one for each. poc et, said rings being attachedon the ends of exihle connections 16. The flexible connectrons 16ersconnected with the commonconductor12, byconductors 17. In the con-`ductors 17 are switches 18 adapted tothe" closed by Apins 19 mounted inthe depressed portions 3. The pins 19. are adapted to be -depressed bythe hinged lids 4 when said pockets 2 are adapted to be engaged by Y' allids are lowered. The rings 15 are adapted v-' to be placed over one ofthe pins 10 and the flexible connections 16 are adapted to be extendedor laced through said pins. This permits the lid to be lowered therebyclosing the r ecjtive switch 18, as will be seen from* the rig t ofeachof Figs. l and 3. The circuits are closed on the checker spaces 8 and 9by metallic checkers 20 shown in Fig. 4. The metallic checkers bridgethe two members 8 and 9 of the checker spaces when placed thereon.

The operatmn of playing the game is briefly as follows: Assuming thatthe player at the rlght end of the board anticipates that the player atthe left will move one of."

his checkers on the lower right hand checker space 8 and 9, he thereuponconnects his ring 15 with the pin 10 corresponding with that checkerspace as is shown diagrammatically in Fig. 3. He then laces theconnection16 throughthe pins 10 and lowers the lid 4.- The lowering ofthe lid 4 closes the respective switch 18 and prevents his changing theselection after once made. When the lid 4 is elevated, it hides the pins10 from the view of the other player, vconsequently it is `not known toone player what move the other player anticipates. If the left playershould then move one o his checkers on said space, the electricalcircuit will be completed through ductor 17, switch 18, flexibleconnection 16, ring 15, pin 10, individual conductor 11, checker'spaceportion 9, checker 20, portion 8, common conductor 12 tothebattery 13. Abell 14 will therefore be sounded. It is contemplated by the rules thata move an-v ticipated by one player and indicated by the bell 14, shallnot player.

I claim, l

1. In a device of thel type specified; a checker board consisting ofchecker spaces forming the terminals of individual split circuits andeach of which consists of two be made by the other,

the battery 13, bell 14, right cons checker s ace, electricallyconnected to one portiono each respective checker space; a commonconductor connecting all the other portions of said checker spaces,electrical connections connected to .said common conductor and adaptedto be connected with said contact points, thereby completing a circuit,and an'energizer, and an indicator in said circuit.

2. In a. device of the type specified; a checker board consistmg ofchecker spaces each of whichconsists of two portions adapted to beelectrically bridged, a checker adapted to electrically bridge saidspaces,

, two contact points for each checker space electrically connected toone portion of their respective checker spaces; a a common con-y ductorconnecting all the other portions of said checker spaces; iiexibl'eelectrical connections connected to said common conductor and adapted tobe connected with said contact points, therebycompleting a circuit; aswitch in each flexible electrical connection; and an energizer and anindicator in said circuit.

3. In a device of the type specified; a

checker board provided'with checker spaces each of which consists of twoelectrically conduct-ing portions, a checker constructed of conductingmaterial and adapted to electrically connect said spaces, a `right and aleft contact point for each checker space electrically connected to oneportion of their respective checker spaces; a common conductorconnect-ing all of the other portions of said checker spaces; fiexibleelectrical connections connected to said common conductor and adapted tobe connected with said contact points, thereby completing a circuit; aswitch in each flexible connection; means controlling access to saidcontact points and also controlling said switches; and an .energizer andan indicatorin said circuit 4. In adevice of the character specified, aser-ies ofy checker spaces each consisting of two separate portions ofconducting material, two oppositely arranged series of contact pointselectrically conducted to one side of each checker space, a commonconductor electrically connected to'the other side of each checkerspace, said common conductor being also electrically connected with twocircuit closing and opening devices, two iexible conductors connectedwith said circuit opening and closing devices and having contact membersadapted to be electrically connected Wtit-hone of the contact points oftheir respective series, shutters adapted to conceal the hand whileselecting the particular contact point for connection with the commoncircuit through one or the other of said flexible conductors, saidshutter being adapted to close one or the other of said circuit closingand opening devices after such selection is made, 'and means such as achecker constructed of conducting material and adapted to be placed onany of said checker spaces to complete the circuit therethrough, and anindicator arranged in the common circuit.

In testimony whereof I aiiix my signature,'in presence of two witnesses.
